The discovery of the H-dibaryon or the \(\Lambda \) n bound state would be a breakthrough in hadron spectroscopy as it would imply the existence of a six-quark state and provide crucial information on the \(\Lambda \) -nucleon and \(\Lambda \) -\(\Lambda \)  interaction.
We consequently have started the investigation on the possible existence of such exotic bound states in pp and Pb–Pb collisions at the LHC. Searches for \(\Lambda \) -nucleon bound states in the \(\Lambda \) p and \(\Lambda \) n channels have been carried out (see references [1]}, [2]}, [3]}).
The H-dibaryon, which is a hypothetical bound state of \(uuddss\)  \(\left(\Lambda \Lambda \right)\) , was first predicted by Jaffe using a bag model approach [4]}. Experimental searches have been undertaken since then, but no evidence for a signal was found (see [5]}, [6]} and references therein). Recently, the STAR collaboration investigated the \(\Lambda \) -\(\Lambda \)  interaction through the measurement of \(\Lambda \Lambda \)  correlations [7]}; this and a theoretical analysis of these data [8]} did not reveal a signal.
Many theoretical investigations of the possible stability of the H-dibaryon have been carried out, but predicting binding energies in the order of MeV for masses of around 2 GeV/\(c^2\)  is extremely difficult and challenging [9]}, [10]}, [11]}, [12]}.
